Claims
I claim:
1. An ostomy bag comprising two walls which are joined together
along a seam around the edge of the bag, one of said two walls
being easily accessible to the user when the bag is in use as it
will face away from the user's skin, the accessible wall including
a closable exit aperture and a closure, which releasably covers the
aperture for selectively releasing accumulated gas through the
aperture, the closure being provided in the form of a sealing flap,
which attaches to the bag by means of a reusable seal, and which
folds down from a hinge formed along the line of the seam, the
hinge being formed by a section of the seam which is substantially
straight, the sealing flap being substantially triangular and
wherein the hinge defines one edge of the triangle, the inner and
outer pouch walls extending beyond the seam to provide the flap,
including a portion of the inner wall and a portion of the outer
wall of the pouch, wherein the flap comprises a disc which is
covered by a reusable adhesive, such that the flap is configured to
be repeatedly peeled away and re-secured to the outer wall of the
pouch, thereby covering the exit aperture; wherein the flap and
exit aperture are configured to release gas from the pouch when the
flap is stored away from the exit aperture; and wherein the flap
and exit aperture are configured to prevent the release of gas from
the pouch when the flap is re-secured to the outer wall of the
pouch.
2. An ostomy bag as claimed in claim 1 wherein the reusable seal
comprises a peelable adhesive.
3. An ostomy bag as claimed in claim 1 wherein the reusable seal is
a mechanical seal comprising an annular rib received in an annular
groove.
4. An ostomy bag as claimed in claim 1 wherein the reusable seal
uses suction.
Description
This application is a 371 U.S. national stage of PCT/GB2012/000032,
filed Jan. 13, 2012, which claims priority to Great Britain
Application No. 1100610.3, filed Jan. 14, 2011. The entire contents
of each of these applications are hereby incorporated by
reference.
The present invention is directed to addressing the problem of
ballooning in ostomy bags and can conveniently be introduced into
any of a wide variety of ostomy bag designs.
Ballooning of a bag arises when there is an accumulation of waste
gases in a partly used bag. The gases cause expansion of the bag
rendering it quite solid to the touch and uncomfortable to wear. It
is not always convenient for a wearer to disrobe and detach or
empty the bag to address this problem. Some gas can be released
through a filter provided in the bag but the speed of gaseous
release provided by the filter is often not fast enough to provide
timely relief to the user.
The present invention provides a convenient solution to the problem
of ballooning.
In accordance with the present invention there is provided an
ostomy bag including in an accessible wall a closable exit aperture
and means for selectively releasing accumulated gas through the
aperture.
The exit aperture can conveniently be resealably opened by a
closure which covers the aperture and attaches to the bag by means
of a peelable adhesive. The closure may conveniently be provided in
the form of a sealing flap which folds down from a seam around the
edge of the bag. Alternatively, the closure may comprise a patch
which can be completely detached from the bag and optionally
replaced with another. Alternative resealable means to a peelable
adhesive will no doubt occur to the skilled addressee and include,
without limitation, a mechanical seal comprising an annular rib
received in an annular groove or a suction based closure means;
Velcro.RTM. or similar.
Preferably, the seam is a welded seam, for example a heat welded
seam.
Preferably, the sealing flap is hinged to the body of the ostomy
bag along the line of the seam. This provides the advantage that
the seam provides a hinge.
Preferably, the hinge is formed by a section of seam which is
straight.
In use, when ballooning occurs, the user can discreetly remove the
closure, gently squeeze the bag and release gas to return the bag
to a comfortable size.
In other options, a valve might be used to close the exit aperture,
the valve being easily activated by the user, for example by
depressing or nipping an area around the aperture.
An embodiment of the invention will now be described with reference
to the accompanying figures in which;
FIG. 1 shows a face on view of an embodiment of the invention with
the exit aperture closed
FIG. 2 shows a face on view of the embodiment of FIG. 1 with the
exit aperture open
FIG. 1 shows an external wall 1 of an ostomy bag which, in use,
would face away from the user's skin and so is easily accessible to
the user. A seam 2 around the periphery of the wall secures two
walls together to form the bag. A filter 3 is located on the front
of the wall for filtering odours and gradually releasing gaseous
products from the bag.
In a corner of the wall 1 is a flap 4 which extends from the seamed
region 2 and is folded onto the wall 1.
FIG. 2 shows the same embodiment with the flap 4 folded back away
from the wall 1. This exposes an exit aperture 5 in the wall 1. On
the under surface of the flap 4 can be seen a disc 6 which is
covered in a reusable adhesive allowing the flap 4 to be repeatedly
peeled away and re-secured to the wall 1 for the useful life of the
bag.
In use, when the bag becomes inflated and uncomfortable, the user
pulls back the flap 4 opening the exit aperture 5. By gently
squeezing the bag excess gases can be quickly released and the
aperture re sealed to prevent leakage of any remaining content in
the bag.
